SMOK TFV9 Replacement Tank

Eight colours. That alone tells you SMOK expects this tank to sell. The TFV9 is a 28mm sub-ohm DTL Tank running V9 mesh coils at 0.15 ohm, with a childproof locking swivel top-fill, dual adjustable bottom airflow, a Pyrex bubble glass section holding 2ml under UK TPD, and a 510 thread that screws onto any mod you already own.

Cross-compatible with V8 Baby 0.15 ohm coils if you have those lying around. Stainless steel construction, massive airflow channels, and a top cap that locks shut so it does not open in your pocket. Over 18s only.

Why vapers choose this:

• V9 mesh at 0.15 ohm for dense DTL cloud and strong flavour at sub-ohm wattages

• Dual adjustable bottom airflow with wide channels. Open for maximum air, tighten for a restricted DTL pull.

• Childproof locking swivel top-cap that stays closed until you deliberately unlock and twist it

• Cross-compatible with V8 Baby 0.15 ohm coils. One tank, two coil families.

• Eight colour options from Matte Black through to Rainbow. More finishes than most tanks offer.

SMOK TFV9 Replacement Tank Features

The Airflow Channels Are Genuinely Massive

Two dual airflow slots carved into the base of the tank. Open them fully, and the TFV9 pulls air like a chimney. The draw at maximum airflow is about as loose as DTL gets without moving to an RDA. Tighten them down, and you get a restricted DTL pull that concentrates the flavour. The adjustment ring rotates smoothly and stays where you set it. If you have used older SMOK tanks where the airflow ring drifted over time, the TFV9 ring holds its position better.

The Top-Fill Locks and That Matters More Than You Think

The locking swivel top-cap requires you to push down and twist before the fill port opens. Childproof by design. But the practical benefit goes beyond child safety: the cap does not accidentally slide open in a pocket, a bag, or a tool belt. Older tanks with simple swivel tops would shift open under pressure and leak liquid everywhere. The TFV9 mechanism prevents that. Push, twist, fill, twist back. Locked.

V9 Mesh Coils and V8 Baby Backward Compatibility

The TFV9 ships with a V9 Mesh 0.15 ohm coil pre-installed. SMOK designed this coil specifically for the TFV9 airflow path. But the tank also accepts V8 Baby 0.15 ohm coils, which means if you are upgrading from a TFV8 Baby tank or a SMOK kit that used V8 Baby coils, your existing stock is not wasted. Grab SMOK Replacement Coils in whichever family suits you.

Bubble Glass Holds the Full 2ml Without Feeling Cramped

The Pyrex bubble glass section curves outward slightly from the 28mm base, which maximises the internal volume within the 2ml TPD limit. The shape also makes the liquid level easier to read because the glass is wider in the middle where you spend most of your time checking. A replacement glass tube ships in the box, which is useful because bubble glass is more exposed to knocks than straight-walled tanks.

28mm Diameter Handles High Wattage Without Overheating

Wider tanks dissipate heat better than narrow ones. At sub-ohm wattage through a 0.15 ohm mesh coil, the TFV9 generates real heat during extended sessions. The 28mm stainless steel body spreads that thermal load across a larger surface area, which keeps the tank comfortable to touch and the liquid at a stable temperature. Narrower tanks at the same wattage get noticeably warmer.

How to Set Up the SMOK TFV9 Replacement Tank

1. The V9 Mesh 0.15 ohm coil comes pre-installed. Before filling, tilt the tank and drip a few drops of High-VG E-Liquid onto the cotton visible through the coil's mesh openings. This pre-saturates the wicking.

2. Push down on the locking top-cap and twist it open. The fill port appears. Pour in your e-liquid. Twist the cap back and release to lock.

3. Stand the tank upright for seven to eight minutes. The 0.15 ohm mesh coil has dense cotton that absorbs slowly on the first fill. Cutting this short means a charred first draw.

4. Screw the tank onto your 510 mod. Set wattage to the low end of the coil's range. Take a gentle first pull. Increase wattage over the next few draws as the coil beds in.

5. Adjust the dual bottom airflow ring to your preferred draw tightness.

What's in the SMOK TFV9 Replacement Tank Box

• The TFV9 tank in your chosen colour with a V9 Mesh 0.15 ohm coil already installed. 

• One replacement Pyrex bubble glass tube. 

• User manual. 

No mod, no battery, no e-liquid. You need a 510 mod and sub-ohm shortfills to use this tank.

Fits Any 510 Mod and Runs Two Coil Families

The TFV9 screws onto any mod with a 510 connection. At 28mm diameter, check your mod's width to confirm a flush fit. Most box mods handle 28mm without issue. Pen mods and compact devices may see overhang.

Two coil families work in this tank: V9 Mesh 0.15 ohm and V8 Baby 0.15 ohm. Both are sub-ohm mesh coils built for DTL wattage. Replacement Coils are stocked across the SMOK Range.

E-liquid: 70/30 or higher VG at 3 to 6mg freebase. Sub-ohm at 0.15 ohm. Do not run nic salts above 6mg through this tank.

About SMOK

SMOK sits under IVPS International Limited in Shenzhen and has been producing vape hardware since before most of the brands on this page launched. The TFV tank series started with the TFV4, went through the TFV8, TFV12, TFV16, TFV18, and now the TFV9 carries the family forward in a more compact, TPD-friendly format.

SMOK's scale means coils and replacement glass for any TFV model are available in practically every UK vape shop, which is a genuine advantage when you need parts quickly.

Stock Up and Save

One coil in the box. One. Once that V9 mesh wears out, you need replacements. A five-pack of V9 coils alongside the tank covers your first month. Every tank ships boxed with the glass section protected to prevent breakage during delivery.

We check age before sending, dispatch same-day on orders before 4 pm, and track every parcel. Over 18s only. Spend £25 or more and Free Pirate Post takes care of shipping.

Conclusion

The TFV9 is SMOK's sub-ohm DTL tank scaled down to 2ml for the UK market. Dual bottom airflow, V9 mesh coils, V8 Baby cross-compatibility, a childproof locking top-fill that actually stays locked, and eight colour options.

At 28mm, it is built for box mods, and it handles high-wattage DTL vaping with the kind of airflow and heat management that narrower tanks struggle with. If you need a replacement sub-ohm tank with wide coil availability and a colour that matches your mod, the TFV9 covers both. Pick one up at Pirate Vapes.

FAQs

What coils fit the TFV9?

V9 Mesh 0.15 ohm (designed for this tank) and V8 Baby 0.15 ohm (cross-compatible). Both are sub-ohm mesh coils for DTL vaping.

Does the TFV9 leak?

The childproof locking top-cap prevents accidental opening. Bottom airflow tanks can seep if the coil is not seated properly or the O-rings are worn. Replace O-rings periodically and make sure the coil sits straight.

What e-liquid works in the TFV9?

70/30 or higher VG at 3 to 6mg freebase. Sub-ohm mesh at 0.15 ohm. Nic salts above 6mg will be uncomfortably harsh.

Will the TFV9 fit my mod?

Any mod with a 510 thread. Check width: the TFV9 is 28mm in diameter, so compact or narrow mods may see overhang. Most box mods handle it without issue.

Does the TFV9 come with a spare glass?

Yes. One replacement Pyrex bubble glass tube is in the box.
